Abstract
Embodiments of the present disclosure provide a method of manufacturing a display substrate. The method includes: forming a first electrode layer on a substrate, the first electrode layer including a plurality of first electrodes arranged in an array; performing a surface treatment on the plurality of first electrodes, such that an affinity of a surface of each of the plurality of first electrodes gradually increases from a central portion of the surface to a peripheral portion of the surface around the central portion, or the affinity of the central portion of the surface is less than the affinity of the peripheral portion of the surface; and forming a light emitting functional layer on the surfaces of the plurality of first electrodes subjected to the surface treatment. Embodiments of the present disclosure further provide a display substrate, a display panel, and a mask.
